Feels like a straw man argument. An attack on the authors character to derail the conversation and additionally a false argument about what it is to be a man.

In this day and age I don’t need protection, but I do need bros to open their eyes and ears, to see what is happening to the other half of the race. And if you’re referring to physical protection — did you not notice that the military is open to both sexes. Like someone aptly commented earlier, what era are you in?
